How important it is to protect your skin in summer and winter

“UV rays can be present at varying intensities throughout the day, even on cloudy days. UVA rays can penetrate clouds and glass, while others reflect off surfaces like water and snow. That is why it is important to protect the skin from the sun, regardless of the season, sunny or not. »

UVA and UVB rays: how do they affect the skin?

“These types of UV rays are differentiated by their wavelength and the height at which they reach the skin. UVA rays make up 95% of radiation and are particularly responsible for skin aging, can damage its DNA or cause cancer. UVB rays, which make up only 5% of the radiation we are exposed to every day, are responsible for tanning and sunburn.[1]. »

cancer prevention

“More than 80,000 cases of skin cancer are diagnosed in Canada each year – including 5,000 melanomas, the deadliest form. Canadians born in the 1990s are two to three times more likely to develop skin cancer in their lifetime (1 in 6 people) than those born in the 1960s (1 in 20).[2] “, specifies the DD Dayeh only. These worrying statistics are proof that it is necessary to adopt good daily protective habits against UV rays.


Science and statistics don’t lie. So how do you protect your skin from the sun? In addition to applying a broad spectrum sunscreen – which protects against both UVA and UVB rays – with an SPF of 30 or higher, here are some good things to do.

1. Stay in the shade as much as possible and avoid sun exposure between 11am and 3pm.

2. Wear protective clothing and accessories made from UV-blocking materials.

3. Apply your sunscreen 15 minutes before sun exposure and reapply regularly.

4. Avoid using tanning equipment.

Sunscreen, a product that should be chosen with care

Sunscreens are not all formulated the same way. Some contain organic filters – sometimes called “chemicals” – that remain on the outer layers of skin to absorb UV rays, and others contain mineral filters that settle on the skin’s surface, reflecting and absorbing harmful rays. Both types of formulations are effective and recommended by dermatologists. However, the differences go beyond the type of filter used and concern texture, technology and ingredients. So take the time to choose your sunscreen wisely and look out for the Canadian Dermatology Association’s identifying logo and the circled UVA logo, which guarantees UVA protection even better than ordinary broad-spectrum protection.
